Fuel tank trailer

Abstract

A fuel tank trailer has a fuel tank supported on the bed of the trailer, and a secondary containment wall surrounding the fuel tank to provide an open secondary containment region. A drain valve controls the flow of fuel and water collecting in the secondary containment region. A fuel separation filter separates the fuel from any water draining from the secondary containment region.

1. A fuel tank trailer comprising:
 a fuel tank; 
 a trailer having a bed supporting the fuel tank; 
 a secondary containment wall surrounding the fuel tank on the trailer providing an open secondary containment region for collection of any fuel leaking from the fuel tank; 
 a drain valve controlling the flow of fuel and any water collecting in the secondary containment region; 
 a fuel separation filter operatively associated with the drain valve for separating the fuel from any water draining through the drain valve from the secondary containment region; and 
 a spill clean-up kit containing materials for cleaning up fuel spills and selectively attachable to the trailer. 
 
   
   
     2. The fuel tank trailer of  claim 1  wherein the secondary containment wall extends around the perimeter of the bed of the trailer. 
   
   
     3. A fuel tank trailer comprising:
 a fuel tank; 
 a trailer having a bed supporting the fuel tank; 
 a secondary containment wall surrounding the fuel tank on the trailer providing an open secondary containment region for collection of any fuel leaking from the fuel tank; 
 a drain valve controlling the flow of fuel and any water collecting in the secondary containment region; 
 a fuel separation filter operatively associated with the drain valve for separating the fuel from any water draining through the drain valve from the secondary containment region; and 
 the drain valve is in the bed of the trailer. 
 
   
   
     4. A fuel tank trailer of comprising:
 a fuel tank; 
 a trailer having a bed supporting the fuel tank; 
 a secondary containment wall surrounding the fuel tank on the trailer providing an open secondary containment region for collection of any fuel leaking from the fuel tank; 
 a drain valve controlling the flow of fuel and any water collecting in the secondary containment region; 
 a fuel separation filter operatively associated with the drain valve for separating the fuel from any water draining through the drain valve from the secondary containment region; and 
 the secondary containment region is open for visual inspection to detect leakage of fuel from the fuel tank. 
 
   
   
     5. The fuel tank trailer of  claim 1  wherein the fuel separation filter comprises a bucket containing filter material retaining the fuel, and wherein the bucket has holes allowing drainage of water from the bucket. 
   
   
     6. The fuel tank trailer of  claim 5  wherein the filter material comprises a cellulose pulp core and an outer layer of polypropylene. 
   
   
     7. The fuel tank trailer of  claim 1  wherein the trailer further comprises wheels. 
   
   
     8. A fuel tank trailer comprising:
 a fuel tank; 
 a trailer having a bed supporting the fuel tank; 
 a secondary containment wall surrounding the fuel tank on the trailer providing an open secondary containment region for collection of any fuel leaking from the fuel tank; 
 a drain valve controlling the flow of fuel and any water collecting in the secondary containment region; 
 a fuel separation filter operatively associated with the drain valve for separating the fuel from any water draining through the drain valve from the secondary containment region; and 
 a polymeric coating on the surfaces of the secondary containment region. 
 
   
   
     9. A fuel tank trailer comprising:
 a fuel tank; 
 a trailer having; 
 (a) wheels; 
 (b) a bed supporting the fuel tank; 
 (c) a secondary containment wall extending around the perimeter of the bed of the trailer defining an secondary containment region surrounding the fuel tank that is open for visual inspection to detect leakage of fuel from the fuel tank; and 
 (d) a drain valve controlling the flow of fuel and any water collecting in the secondary containment region; and 
 a fuel separation filter operatively associated with the drain valve for separating the fuel from any water draining through the drain valve from the secondary containment region. 
 
   
   
     10. The fuel tank trailer of  claim 9  wherein the drain valve is in the bed of the trailer. 
   
   
     11. The fuel tank trailer of  claim 9  wherein the fuel separation filter comprises a bucket containing filter material retaining the fuel, and wherein the bucket has holes allowing drainage of water from the bucket. 
   
   
     12. The fuel tank trailer of  claim 11  wherein the filter material comprises a cellulose pulp core and an outer layer of polypropylene. 
   
   
     13. The fuel tank trailer of  claim 9  further comprising a polymeric coating on the surfaces of the secondary containment region. 
   
   
     14. A fuel tank trailer comprising:
 a fuel tank; 
 a trailer having; 
 (a) a bed supporting the fuel tank; 
 (b) a secondary containment wall surrounding the fuel tank on the trailer providing an open secondary containment region for collection of any fuel leaking from the fuel tank; and 
 (c) a drain valve controlling the flow of fuel and any water collecting in the secondary containment region; 
 a fuel separation filter operatively associated with the drain valve for separating the fuel from any water draining through the drain valve from the secondary containment region having: 
 (a) a bucket with holes allowing water to escape from the bucket; and 
 (b) filter material within the bucket retaining any fuel; and 
 a polymeric coating on the surfaces of the secondary containment region. 
 
   
   
     15. The fuel tank trailer of  claim 14  wherein the secondary containment wall extends around the perimeter of the bed of the trailer. 
   
   
     16. The fuel tank trailer of  claim 14  wherein the filter material comprises a cellulose pulp core and an outer layer of polypropylene.
